How to detect the current language of a Joomla! website?

Question

I just want to generate a code that will detect the current language of my websit in joomla + php

See getLanguage in JFactory:

$lang =& JFactory::getLanguage();
echo 'Current language is: ' . $lang->getName();

Once you have the language, you can also retrieve the locale/language code (e.g. en-US). Joomla! languages can have multiple locales, so you'll get an array.

$lang =& JFactory::getLanguage();
foreach ($lang->getLocale() as $locale) {
    echo 'This language supports the locale: ' . $locale;
}

If, for some reason, you're only interested in the first locale, you can simply grab the first element. You will probably need an array, like this:

$lang =& JFactory::getLanguage();
$locales = $lang->getLocale();
echo 'This language's first locale is: ' . $locales[0];
